The Passenger in the Oven - S4-E10
Continuity mistake: When Booth sneaks into 1st class at the start Bones slides her eye mask up on her forehead. A few shots later, without touching her mask, it is now a lot higher on her forehead. (00:02:15)

Continuity mistake: Hodgins takes the lid off the fish blender twice when trying to find out what killed the fish. (00:32:00)

The Beaver in the Otter - S4-E24
Character mistake: About half way through the episode, there is a computer screen with "Chemsitry" on it - a spelling error that should not have made it past editing. (00:24:10)
Other mistake: Early in the episode, when the body from the outhouse is in the lab, the gang are all wearing bio-hazard suits. Sweets' suit has an opening along the rear-left section of the facemask - perhaps 3" long, and a half-inch high - making the point of the suit completely useless. (00:05:10)
The Critic in the Cabernet - S4-E25
Continuity mistake: Hodgins and Fisher are discussing how hard it is to remove wine stain. Hodgins' rubber gloves are very dirty. When Fisher realizes how to clean the bones, Hodgins' gloves are much cleaner, only stained around the finger tips.
Factual error: Dr. Wexler is killed in his flat in Oxford, yet the the fire engine outside his property is marked as being from the London Fire Brigade rather than the Oxfordshire Fire and Rescue Service. (00:04:20)
Chosen answer: Pickering states the name "Juan Guzman" and during the run of the show we are never told who he is, or why Brennan had been in Cuba and met with this Juan Guzman. We don't know if there is any kind of "relationship" between Brennan and Guzman. A bit frustrating, but I like how this short scene shuts down Agent Pickering's entire review, and it hints at Brennan's career history and her level of security clearance.

Thanks for the clarification. It's been a while since I watched the series start to finish. It also adds to show how much power Brennan actually has.

Do you remember when Bones was telling Angela about the time she was on one of her out of the country trips, and she was thrown in a dark cell for what she later found out was 3 days? She was crying and looked terrified as she remembered this. She had that same look as someone who was remembering past trauma when Pickering said this name. I kind of always thought that "Juan Guzman" was the one who did that.
